Giving a test to a group of students, the grades and gender are summarized below A B C Total Male 10 7 13 30 Female 3 5 8 16 Total 13 12 21 46 Write all solutions as a decimals to 4 places. If one student is chosen at random, ---------------------------------------------- Find the probability that the student was male: Number of male students = 30 Total number of students = 46 P(Male) = 30/46 = 0.6522 ----------------------------------------------- Find the probability that the student was male AND got a "C": P(Male and C) = 13/46 = 0.2826 ----------------------------------------------- Find the probability that the student was male OR got a "C": P(Male OR C) = P(Male)+P(C)-P(Male AND C) P(Male OR C) = 30/46 + 21/46 - 13/46 = 38/46 = 0.8261 ---------------------------------------------------- If one student is chosen at random, find the probability that the student got a C' GIVEN they are male. P(C|Male) = P(C AND Male)/P(Male) = Edwin
